more of the Affiliates, if so elected or appointed from time to time.

                  b. You agree to perform the duties of your position and such
other duties, consistent with your position, as may reasonably be assigned to
you from time to time. You also agree that, while employed by the Company, you

of the Company and the Affiliates and to the discharge of your duties and
responsibilities to them.

         2. COMPENSATION AND BENEFITS. During your employment, as compensation

will be eligible to earn a bonus of up to seventy-five percent (75%) of your
base salary for each full calendar year during your employment with the Company,
based on the Company's achievement of objectives which you and the Board shall
mutually determine from time to time. This bonus shall be awarded, if at all,

                  c. STOCK OPTIONS. On the effective date of this agreement (as
set forth in Section 1.a above), the Company shall grant you an option to

         Company policies.

                  ii. In addition to the foregoing, during your employment, the

Section 2.e, "living expenses" shall include reasonable costs for lodging,
meals, laundry, groceries, dry cleaning, and telephone calls, but will not
include expenses that normally would be incurred by you if you were not
relocating such as, but not limited to, mileage to and from work, car insurance
and car repairs.

         3. CONFIDENTIAL INFORMATION AND RESTRICTED ACTIVITIES.

                  a. CONFIDENTIAL INFORMATION. During the course of your
employment with the Company, you will learn of Confidential Information, as
defined below, and you may develop Confidential Information on behalf of the
Company and the Affiliates. You agree that you will never use or disclose to any
Person (except as required by applicable law or for the proper performance of
your duties and responsibilities to the Company and the Affiliates) any
Confidential Information. You understand that this restriction shall continue to
apply after your employment terminates, regardless of the reason for such
termination.

                  b. PROTECTION OF DOCUMENTS. All documents, records and files,
in any media of whatever kind and description, relating to the business, present
or otherwise, of the Company and the Affiliates and any copies ("Documents"),
whether or not prepared by you, shall be the sole and exclusive property of the
Company and the Affiliates. You agree to safeguard all Documents and to
surrender to the Company, at the time your employment terminates or at such
earlier time or times as the Company may specify, all Documents then in your
possession or control.

                  c. NON-COMPETITION. You acknowledge and agree that the
following restrictions on your activities during and after your employment are
necessary to protect the goodwill, Confidential Information and other legitimate
interests of the Company and the Affiliates:

                  i. While you are employed by the Company and during the period
         of one year immediately following termination of your employment (the
         "Non-Competition Period"), you shall not, directly or indirectly,
         whether as owner, partner, investor, consultant, agent, employee,
         co-venturer or otherwise, compete with the Company or be associated
         with any competitor of the Company. The foregoing shall not prevent
         your passive ownership of three percent (3%) or less of the equity
         securities of any publicly-traded company.

                  ii. You agree that during the Non-Competition Period, you will
         not, directly or indirectly, (1) hire or solicit for hiring any
         employee of the Company or any of the Affiliates or any person who has
         been such an employee in the preceding three months or seek to persuade
         any employee of the Company or any of the Affiliates to discontinue
         employment, (2) solicit or encourage any customer of the Company or any
         of the Affiliates or independent contractor providing services to the
         Company or any of the Affiliates to terminate or diminish its
         relationship with them or (3) seek to persuade any customer or
         prospective customer of the Company or any of the Affiliates to conduct
         with anyone else any business or activity that such customer or
         prospective customer conducts or could conduct with the Company or any
         of the Affiliates.

                  e. ASSIGNMENT OF INTELLECTUAL PROPERTY. You agree to promptly
and fully disclose to the Company all Intellectual Property, as defined below.
You hereby assign and agree to assign to the Company (or as otherwise directed
by the Company) your full right, title and interest to all Intellectual
Property. You further agree to execute any and all applications for domestic and
foreign patents, copyrights and other proprietary rights and do such other acts
(including, among others, the execution and delivery of instruments of further
assurance or confirmation) requested by the Company to assign the Intellectual
Property to the Company and to permit the Company to enforce any patents,
copyrights and other proprietary rights in the Intellectual Property. You agree
that you will not charge the Company for time spent in complying with these
obligations. All copyrightable works that you create shall be considered "work
made for hire."

                  f. You agree that, until the expiration of the Non-Competition
Period, you will provide the Company with such pertinent information concerning
your business activity as the Company may reasonably request in order to
determine your continued compliance with your obligations under this Section 3.
You agree to inform any new or prospective employer of this agreement and of
your obligations under this Section 3.

                  g. In signing this agreement, you give the Company assurance
that you have carefully read and considered all the terms and conditions of this
agreement, including the restraints imposed on you under this Section 3. You
agree without reservation that these restraints are necessary for the reasonable
and proper protection of the Company and the Affiliates; that each and every one
of the restraints is reasonable in respect to subject matter, length of time and
geographic area; and that these restraints will not prevent you from obtaining
other suitable employment during the Non-Competition Period. You further agree
that, were you to breach any of the covenants contained in this Section 3, the
damage to the Company and the Affiliates would be irreparable. You therefore
agree that the Company, in addition to any other remedies available to it, shall
be entitled to preliminary and permanent injunctive relief against any breach or
threatened breach by you of any of those covenants, without having to post bond,
and that you will not take, and you will not permit anyone else to take on your
behalf, any position in a court or any other forum inconsistent with any of your
covenants and agreements herein. You and the Company further agree that, in the
event that any provision of this Section 3 is determined by any court of
competent jurisdiction to be unenforceable by reason of its being extended over
too great a time, too large a geographic area or too great a range of
activities, that provision shall be deemed to be modified to permit its
enforcement to the maximum extent permitted by law. It is also agreed that each
of the Affiliates shall have the right to enforce all of your obligations to
that Affiliate under this agreement, including without limitation pursuant to
this Section 3.

         4. TERMINATION OF EMPLOYMENT. Your employment under this agreement
shall continue until terminated pursuant to this Section 4.

<PAGE>

                  a. BY THE COMPANY (i) The Company may terminate your
employment other than for Cause at any time upon six months' notice; provided,
however, that the Company may elect to pay you your base salary for some or all
of the six month period in lieu of notice. (ii) The Company may terminate your
employment for Cause upon notice to you setting forth in reasonable detail the
nature of the Cause. Only the following shall constitute Cause for termination:
(1) your willful failure to perform (other than by reason of disability), or
gross negligence in the performance of, your duties and responsibilities to the
Company or any of the Affiliates; (2) your material breach of any provision of
Section 3 of this agreement; or (3) other serious misconduct by you that is
reasonably anticipated to result in material injury to the business, interests
or reputation of the Company or any of the Affiliates; provided, however, that
to the extent that the acts or omissions giving rise to such termination are
capable of being cured by you, you will be afforded 30 days to correct such acts
or omissions specified in the termination notice provided by the Company.

                  b. BY YOU. You may terminate your employment, other than for
Good Reason or for Good Reason, upon six months' notice to the Company. If you
terminate for Good Reason, the notice must set forth in reasonable detail the
nature of such Good Reason. In the event of your termination of your employment
hereunder, the Company may elect to waive some or all of the notice period and,
in that event, shall continue to pay you your base salary and benefits for that
portion of the notice period waived. Only the following shall constitute Good
Reason for termination: (a) the Company's assignment of any duties to you that
are materially inconsistent with your positions, duties, responsibilities or
reporting requirements with the Company, (b) the Company's material reduction of
your responsibilities, authority or status with the Company, (c) the Company's
reduction of your compensation or any benefit provided by this Agreement or (d)
the Company's material breach of its obligations under this Agreement or any
other material agreement between the Company and you; provided, however, that to
the extent that the acts or omissions giving rise to such termination are
capable of being cured by the Company, the Company will be afforded 30 days to
correct such acts or omissions specified in the termination notice provided by
you.

                  c. BY REASON OF DISABILITY. In the event you become disabled
during employment through any illness, injury, accident or condition of either a
physical or psychological nature and, as a result, are unable to perform
substantially all of your duties hereunder, the Company will continue to pay you
your base salary, less the amount of any benefits provided you through a
Company-provided disability plan, and will continue to provide you benefits in
accordance with Section 2.d above for up to six months of disability during any
rolling period of three hundred and sixty-five (365) consecutive calendar days.
If you are unable to return to work after six months of disability, the Company
may terminate your employment, upon notice to you. If any question shall arise
as to whether you are disabled to the extent that you are unable to perform
substantially all of your duties



                                     - 6 -
<PAGE>

hereunder, you shall, at the Company's request, submit to a medical examination
by a physician selected by the mutual agreement of you (or your guardian, if
any) and the Company to determine whether you are so disabled and such
determination shall for the purposes of this agreement be conclusive of the
issue. If such a question arises and you fail to submit to the requested medical
examination, the Company's determination of the issue shall be binding on you.


         5. SEVERANCE PAYMENTS AND OTHER MATTERS RELATED TO TERMINATION.

                  a. In the event of termination of your employment by the
Company other than for Cause in accordance with Section 4.a.i. or by you for
Good Reason in accordance with Section 4.b, and provided that no severance
benefits are payable to you under the change of control agreement between you
and the Company of even date (the "Change of Control Agreement"), the Company
will, notwithstanding that you may have become employed by another employer,
continue to pay you your base salary and continue to provide all of your group
health and life insurance benefits, including the benefit provided by Section
2.d.ii, for a period of twelve months (the "Severance Pay Period"). The Company
will also pay you on the date of termination any base salary and bonus
compensation earned but not paid through the date of termination (including a
pro-rated portion of any earned bonus for the year in which the termination
occurs) and pay for any Paid Time Away accrued but not used to that date. In
addition, all options granted you by the Company shall become exercisable on the
date of termination and shall remain exercisable for one year following the date
of termination.

                  b. Severance payments will be in the form of salary and
benefits continuation, payable in accordance with the normal payroll practices
of the Company and will begin on the Company's next regular payday following the
effective date of termination of your employment or, in the event that the
Company elects to provide you pay in lieu of notice for some or all of the
notice period, on the Company's next regular payday following the period for
which pay is provided in lieu of notice; provided, however, that coverage under
the Company's group health plan will terminate at such time as you and/or your
dependents become eligible for coverage under the health plan of another
employer. Your participation in all other employee benefit plans and programs
other than those specified in Section 5.a will cease as of the date of
termination of your employment, without regard to any continuation of base
salary or other payment to you following termination.

                  c. In the event of termination of your employment by you or by
the Company for Cause, the Company will pay you (i) any base salary earned but
not paid through the date of termination, (ii) bonus for any prior year that was
granted but not paid and bonus for the current year prorated through the date of
termination, and (iii) pay for



                                     - 7 -
<PAGE>

any Paid Time Away accrued but not used to that date, but shall have no further
obligation to you. All unvested options granted you by the Company shall be
forfeited in the event of termination of your employment for Cause.

                  d. Provisions of this agreement shall survive any termination
if so provided in this agreement or if necessary or desirable to accomplish the
purpose of other surviving provisions, including without limitation your
obligations under Section 3 of this agreement. The obligation of the Company to
make payments to you in lieu of notice under Section 4.a or 4 b hereof or
severance payments under Section 5.a is expressly conditioned upon your
continued full performance of your obligations under Section 3 hereof.
